With tensions mounting in Hungary following the Nazi invasion of Poland and war declared between Britain and Germany, the Church of Scotland wrote repeated letters asking Jane to come home - but she refused, saying: “If these children need me in days of sunshine, how much more do they need me in these days of darkness?”

In March 1944, Nazi troops marched into Budapest. Soon after, Jane was arrested by the Gestapo for suspected espionage on behalf of Britain.

She was forced to leave behind the 400 children in her care and sent to the labour camps at Auschwitz - by then it was also an extermination camp where more than one million people were killed, many sent straight to the gas chambers.

It is known that Jane survived two months, but not how she died - her death certificate simply reads: 'cachexia following intestinal catarrh'.

She is the only Scot to be officially recognised at Yad Vashem, the Holocaust remembrance authority in Jerusalem, and there are memorials dedicated to her in Budapest.

Back in Glasgow, Queen’s Park Church erected two stained glass windows in 1997, titled Service and Sacrifice, in her honour.

But it’s a story that the South Glasgow Heritage and Environment Trust and TRAM Direct Theatre Company hoped to spread further.

In 2012, the theatre co produced To Serve is to Resist, a play based on the missionary's life and written by Clarkston man Ian Morland.

The story of Jane Haining returns to the stage this month as part of the Southside Fringe, and artistic director Isobel Barrett hopes it will be another sell-out success.
